Diplotene

Vedclass · Answer

(B) In meiosis-$I$, the prophase-$I$ is divided into five sub-stages: Leptotene, Zygotene, Pachytene, Diplotene, and Diakinesis.$1$. During $Zygotene$, homologous chromosomes pair up, a process known as synapsis.$2$. During $Pachytene$, crossing over occurs between non-sister chromatids of homologous chromosomes.$3$. During $Diplotene$, the synaptonemal complex dissolves, and the homologous chromosomes begin to separate from each other, except at the sites of crossovers, which are called chiasmata.Therefore, the phase where chromosomes begin to separate is $Diplotene$.

Column $I$	Column $II$
$A$. Leptotene	$i$. Nucleolus disappears
$B$. Zygotene	$ii$. Formation of recombination nodules
$C$. Pachytene	$iii$. Development of synapsis
$D$. Diplotene	$iv$. Chromosomes appear as thread-like structures
$E$. Diakinesis	$v$. Gene exchange occurs via chiasmata
